SUMMARY

The disclosure provides an electronic device including an area with improved transmittance in an active area.

The disclosure provides a display panel having a uniform lifespan over a display area with respect to a selected luminance and having improved lifespan in the display area corresponding to an electronic module.

Embodiments provide an electronic device that may include a display panel including a first area including a light blocking area and a transmission area, a first pixel disposed in the first area, a second area adjacent to the first area, and a second pixel disposed in the second area, an input sensor disposed on the display panel, the input sensor including at least one insulating layer and a conductive layer, a black matrix disposed on the at least one insulating layer, a first color filter layer disposed on the at least one insulating layer, the first color filter overlapping the first pixel in a plan view, and a second color filter layer disposed on the at least one insulating layer, the second color filter overlapping the second pixel in a plan view. A thickness of the first color filter layer may be smaller than a thickness of the second color filter layer.

The thickness of the first color filter layer may be equal to or greater than about 60% of the thickness of second color filter layer and may be equal to or smaller than about 90% of the thickness of the second color filter layer.

A difference between the thickness of the first color filter layer and the thickness of the second color filter layer may be equal to or greater than about 0.3 micrometers and may be equal to or smaller than about 1.5 micrometers.

Each of the first pixel and the second pixel may include at least one first sub-pixel, at least one second sub-pixel, and at least one third sub-pixel. Each of the at least one first sub-pixel, the at least one second sub-pixel, and the at least one third sub-pixel may emit a light having a different color from each other. Each of the first color filter layer and the second color filter layer may include a first sub-color filter, a second sub-color filter, and third sub-color filter.

A difference between a thickness of the third sub-color filter of the first color filter layer and a thickness of the third sub-color filter of the second color filter layer may be greater than a difference between a thickness of the first sub-color filter of the first color filter layer and a thickness of the first sub-color filter of the second color filter layer.

An arrangement of the at least one first sub-pixel, the at least one second sub-pixel, and the at least one third sub-pixel of the first pixel, and an arrangement of the at least one first sub-pixel, the at least one second sub-pixel, and the at least one third sub-pixel of the second pixel may be different from each other.

In the first pixel, the at least one first sub-pixel may include two first sub-pixels, the at least one second sub-pixel may include four second sub-pixels, and the at least one third sub-pixel may include two third sub-pixels. The four second sub-pixels may be spaced apart from each other in a first direction. One of the two first sub-pixels and one of the two third sub-pixels may be spaced apart from each other in a second direction intersecting the first direction with the four second sub-pixels interposed between the one of the two first sub-pixels and the one of the two third sub-pixels. Another one of the two first sub-pixels may be spaced apart from the one of the two third sub-pixels in the first direction. Another one of the two third sub-pixels may be spaced apart from the one of the two first sub-pixels in the first direction.

Each of the four second sub-pixels may have a short side extending in the first direction and a long side extending in the second direction. Each of the two first sub-pixels and each of the two third sub-pixels may have a long side extending in the first direction and a short side extending in the second direction. The short side of each of the two first sub-pixels faces the short side of each of the two third sub-pixels that are spaced apart. The long side of each of the two first sub-pixels and the long side of each of the two third sub-pixels face the short side of at least one of the four second sub-pixels.

One of the two first sub-pixels may have right sides that extend in the first direction and may have first connection sides that connect the right sides adjacent to each other. The first connection sides extend in an oblique direction with respect to the first direction and the second direction.

One of the two third sub-pixels may have left sides that extend in the first direction and may have second connection sides that connect the left sides adjacent to each other. The second connection sides may extend in a direction intersecting the oblique direction.

In the second pixel, the at least one second sub-pixel may include two second sub-pixels spaced apart from each other in the second direction. The at least one first and sub-pixel of the second pixel and the at least one third sub-pixel of the second pixel may be spaced apart from each other in the second direction.

In the first pixel, the at least one second sub-pixel and the at least one third sub-pixel may be spaced apart from each other in a first direction. In the first pixel, the at least one first sub-pixel may be spaced apart from the at least one second sub-pixel and the at least one third sub-pixel in a second direction intersecting the first direction. In the first pixel, the at least one second sub-pixel and the at least one third sub-pixel each may have a short side extending in the first direction and a long side extending in the second direction, and the at least one first sub-pixel may have a long side extending in the first direction and a short side extending in the second direction. In the first pixel, the long side of the at least one first sub-pixel may overlap the short side of each of the at least one second sub-pixel and the at least one third sub-pixel, in the second direction.

The second pixel may have a circular shape or a quadrangular shape.

Each of the first pixel and the second pixel may include transistors and a light emitting diode electrically connected to at least one of the transistors. The display panel may include a base layer, a buffer layer disposed on the base layer, and a light blocking layer disposed between the buffer layer and the transistors. The light blocking layer may overlap the light blocking area of the first area in a plan view, and may not overlap the transmission area of the first area in a plan view.

The display panel may include inorganic insulating layers disposed on the light blocking layer and an organic insulating layer disposed on the inorganic insulating layers. The inorganic insulating layers may overlap the transmission area in a plan view and surround a transmission opening that exposes at least a portion of the buffer layer. The organic insulating layer may be disposed in the transmission opening, and may cover the exposed portion of the buffer layer.

The first color filter layer and the black matrix may overlap the light blocking area of the first area, in a plan view, and may not overlap the transmission area of the first area. The second color filter layer and the black matrix may overlap the second area, in a plan view.

The display panel further includes an overcoat layer disposed on the first color filter layer and the second color filter layer. At least a portion of an upper surface of the black matrix may be covered by the first color filter layer and second color filter layer. A portion of the upper surface of the black matrix adjacent to the transmission area may be covered by the first color filter layer. Another portion of the upper surface of the black matrix may be covered by the overcoat layer.

The electronic device further may include an electronic module overlapping the first area in a plan view, the electronic module being disposed under the display panel. The electronic module may include at least one of a light emitting module, a light receiving module, and a camera module.

According to the above, the color filter layer disposed in the area overlapping the electronic module has a thickness thinner than a thickness of the color filter layer disposed in the area that does not overlap the electronic module. As the light transmittance in the area overlapping the electronic module increases, a luminous lifespan is improved. Accordingly, the electronic device has a uniform luminous lifespan over an entire area of the display area.

In the disclosure, it will be understood that when an element (or area, layer, or portion) is referred to as being “on,” “connected to,” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present.

Like numerals refer to like elements throughout. In the drawings, the thickness, ratio, and dimension of components are exaggerated for effective description of the technical content.

In the specification and the claims, the term “and/or” is intended to include any combination of the terms “and” and “or” for the purpose of its meaning and interpretation. For example, “A and/or B” may be understood to mean “A, B, or A and B.” The terms “and” and “or” may be used in the conjunctive or disjunctive sense and may be understood to be equivalent to “and/or.”

In the specification and the claims, the phrase “at least one of” is intended to include the meaning of “at least one selected from the group of” for the purpose of its meaning and interpretation. For example, “at least one of A and B” may be understood to mean “A, B, or A and B.”

It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Thus, a first element discussed below could be termed a second element without departing from the teachings of the disclosure. As used herein, the singular forms, “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature’s relationship to another element(s) or feature(s) as illustrated in the figures.

It will be further understood that the terms “includes” and/or “including” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

“About,” “substantially,” or “approximately” as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “about” may mean within one or more standard deviations, or within ± 30%, 20%, 10%, 5% of the stated value.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Hereinafter, the disclosure will be explained in detail with reference to the accompanying drawings.

FIG. 1 is a schematic perspective view showing an electronic device 1000 according to an embodiment of the disclosure. FIG. 2A is an exploded schematic perspective view showing the electronic device 1000 according to an embodiment of the disclosure. FIG. 2B is a block diagram showing the electronic device 1000 according to an embodiment of the disclosure. FIG. 3 is schematic diagram of an equivalent circuit diagram showing a pixel PXij according to an embodiment of the disclosure.

The electronic device 1000 may be a device activated in response to an electrical signal. The electronic device 1000 may include various embodiments. For example, the electronic device 1000 may include a tablet computer, a notebook computer, a computer, a smart television, or the like. In an embodiment, a smartphone will be described as an example of the electronic device 1000.

The electronic device 1000 may display an image IM through a display surface FS, which is substantially parallel to a plane formed by axes in the first direction DR1 and the second direction DR2. The display surface FS may face toward the third direction DR3. The display surface FS, through which the image IM is displayed, may correspond to a front surface of the electronic device 1000 and a front surface FS of a window 100.

Hereinafter, the display surface and the front surface of the electronic device 1000 and the front surface of the window 100 will be assigned with the same reference numeral. The image IM may include a still image as well as a video. FIG. 1 shows a clock widget and application icons as examples of the image IM.

In an embodiment, front (or upper) and rear (or lower) surfaces of each member of the electronic device 1000 may be defined with respect to a direction in which the image IM is displayed. The front and rear surfaces may be opposite to each other in the third direction DR3, and a normal line direction of each of the front and rear surfaces may be substantially parallel to the third direction DR3. A separation distance between the front and rear surfaces may correspond to a thickness in the third direction DR3 of a display module 300 (refer to FIG. 2A).

According to an embodiment, the electronic device 1000 may sense a user input TC applied thereto from the outside. The user input TC may include various types of external inputs, such as a part of a user’s body, light, heat, or pressure. In an embodiment, the user input TC is shown as a hand of the user applied to the front surface of the electronic device 1000, however, this is merely an example. As described above, the user input TC may be provided in various forms. The electronic device 1000 may sense the user input TC applied to a side or rear surface of the electronic device 1000 depending on its structure, however, it should not be limited to a specific embodiment.

In an embodiment, a first area A1 may be defined in a transmission area TA. The first area A1 may be an area of the display module 300overlapping an electronic module 400. In FIG. 2A, the first area A1 is illustrated as a circular shape disposed at an upper right end, however, the first area A1 should not be limited thereto. According to an embodiment, the first area A1 may have various shapes in the display module 300 depending on the shape of the electronic modules 400, and the number of first areas A1 may vary according to the number of electronic modules 400. However, the embodiments should not be particularly limited.

The electronic device 1000 may receive external signals required for the electronic module 400 via the first area A1 or may provide output signals from the electronic module 400 to the outside via the first area A1. According to the disclosure, as the first area A1 is defined to overlap the transmission area TA, the size of a bezel area BZA defining (or surrounding) the transmission area TA may decrease. This will be described in detail below.

Referring to FIG. 2A, the electronic device 1000 may include the window 100, a housing 200, the display module 300, and the electronic module 400. In an embodiment, the window 100 and the housing 200 may be coupled to each other to provide an exterior of the electronic device 1000.

The window 100 may include an insulating panel. For example, the window 100 may include a glass material, a plastic material, or a combination thereof.

The front surface FS of the window 100 may define the front surface of the electronic device 1000 as described above. The transmission area TAmay be an optically transparent area. For example, the transmission area TA may be an area having a visible light transmittance of about 90% or more.

The bezel area BZA may be an area having a relatively lower transmittance as compared with the transmission area TA. The bezel area BZA may define a shape of the transmission area TA. The bezel area BZA may be disposed adjacent to the transmission area TA and may surround the transmission area TA.

The bezel area BZA may have a selected color. The bezel area BZA may be defined by a bezel layer provided separately from a transparent substrate defining the transmission area TA or may be defined by an ink layer that may be inserted into the transparent substrate, or may be formed by coloring the transparent substrate.

The display module 300 may include an electronic panel EP and a driving circuit IC.

The electronic panel EP may display the image IM and may sense the user input TC (refer to FIG. 1 ). The electronic panel EP may include a front surface IS in which a display area DA and a non-display area NDA are defined. The display area DA may be an area activated in response to an electrical signal.

In an embodiment, the display area DA may be an area where image IM is displayed, and user input TC is sensed. The display area DA may be an area in which pixels PXij, described below, are arranged.

The transmission area TA may overlap at least the display area DA. For example, the transmission area TA may overlap all or at least a portion of the display area DA. Accordingly, the user may view the image IM and may provide the user input TC via the transmission area TA, however, the embodiments are not limited thereto. In other examples, the area through which the image IM is displayed and the area through which the external input TC is sensed may be separated from each other in the display area DA.

The non-display area NDA may be covered by the bezel area BZA. The non-display area NDA may be disposed adjacent to the display area DA. The non-display area NDA may surround the display area DA. The non-display area NDA may be an area through which the image IM is not displayed. A driving circuit or a driving line to drive the display area DA may be disposed in the non-display area NDA.

In an embodiment, the electronic panel EP may be assembled in a flat state in which the display area DA and the non-display area NDA face the window 100, however, the embodiments are not limited thereto. In other examples, a portion of the non-display area NDA of the electronic panel EP may be curved. The portion of the non-display area NDA may be bent toward the rear surface of the electronic device 1000, and thus, the bezel area BZA in the front surface of the electronic device 1000 may be reduced. According to an embodiment, the electronic panel EP may be assembled while a portion of the display area DA is in a curved state. Further, the non-display area NDA may be omitted from the electronic panel EP according to an embodiment of the disclosure.

The display area DA may include the first area A1 and a second area A2. The first area A1 may have a relatively higher light transmittance than that of the second area A2. The first area A1 may be defined as an area of the display module 300, which overlaps an area where the electronic module 400 is disposed in the housing 200. In an embodiment, the first area A1 is shown as having a circular shape, however, the embodiments are not limited thereto. In other examples, the first area A1 may have a variety of shapes, such as a polygonal shape, an oval shape, a shape with at least one curved line, or other shape.

The second area A2 may be defined adjacent to the first area A1. In an embodiment, the second area A2 may surround the entire of the first area A1, however, the embodiments are not limited thereto. In other examples, the second area A2 may be defined adjacent to only a portion of an edge of the first area A1 and should not be particularly limited.

Referring to FIG. 2B, the electronic panel EP of the display module 300 may include a display panel 310 and an input sensor 320. The display panel 310 may include components to generate the image IM (refer to FIG. 1 ). The image IM generated by the display panel 310 may be displayed on the display surface IS (refer to FIG. 2A) through the transmission area TA (refer to FIG. 2A) and viewed by the user.

The input sensor 320 may sense the user input TC (refer to FIG. 1 ) applied thereto from the outside. As described above, the input sensor 320 may sense the user input TC applied to the window 100 (refer to FIG. 1 ).

Referring to FIG. 2A, the electronic panel EP may include a flat portion FN and a bending portion BN. The flat portion FN may be assembled to be substantially parallel to a plane defined by axes in the first direction DR1 and in the second direction DR2. The display area DA may be defined in the flat portion FN.

The bending portion BN may extend and may be bent from the flat portion FN. The bending portion BN may be assembled to be bent from the flat portion FN and disposed on a rear side of the flat portion FN. Since the bending portion BN overlaps the flat portion FN in a plane when being assembled, the bezel area BZA of the electronic device 1000 may decrease. In other examples, and the bending portion BN may be omitted from the electronic panel EP.

The driving circuit IC may be mounted on the bending portion BN. The driving circuit IC may be provided as a chip. However, the embodiments are not limited thereto. In other examples, the driving circuit IC may be electrically connected to the electronic panel EP via a flexible circuit board after being provided to a separate circuit board.

The driving circuit IC may be electrically connected to the display area DA and may apply electrical signals to the display area DA. For example, the driving circuit IC may include a data driving circuit and may apply data signals to pixels arranged in the display area DA. According to an embodiment, the driving circuit IC may include a touch driving circuit and may be electrically connected to the input sensor disposed in the display area DA. In other examples, the driving circuit IC may include additional circuits and may apply a variety of electrical signals to the display area DA, and are not particularly limited.

Although not shown in figures, the electronic device 1000 may further include a main circuit board electrically connected to the electronic panel EP and the driving circuit IC. The main circuit board may include various driving circuits that drive the electronic panel EP as well as a connector to provide power. The main circuit board may be a rigid printed circuit board (PCB), however, in other examples, the main circuit board may be a flexible circuit board, and is not particularly limited.

The electronic module 400 may be disposed under the display module 300. The electronic module 400 may receive the external input via the first area A1 or may output signals via the first area A1. According to the disclosure, as the first area A1 having a relatively high transmittance is defined in the display area DA, the electronic module 400 may be disposed to overlap the display area DA. Accordingly, an increase in size of the bezel area BZA (and an increase in the size of the non-display area NDA) may be prevented.

Referring to FIG. 2B, the electronic device 1000 may include the display module 300, a power supply module PM, a first electronic module EM1, and a second electronic module EM2. The display module 300, the power supply module PM, the first electronic module EM1, and the second electronic module EM2 may be electrically connected to each other.

The power supply module PM may supply power required to operate the electronic device 1000. The power supply module PM may include a battery module.

The first electronic module EM1 and the second electronic module EM2 may include various functional modules to operate the electronic device 1000. The first electronic module EM1 may be mounted directly on a mother board that is electrically connected to the electronic panel EP or may be electrically connected to the mother board via a connector (not shown) after being mounted on a separate substrate.

The first electronic module EM1 may include a control module CM, a wireless communication module TM, an image input module IIM, an audio input module AIM, a memory MM, and an external interface IF. Some modules among the modules may be electrically connected to the mother board through a flexible circuit board without being mounted on the mother board.

The control module CM may control the overall operation of the electronic device 1000. The control module CM may be, but not limited to, a microprocessor. For example, the control module CM may activate or deactivate the display module 300. The control module CM may control other modules, such as the image input module IIM, the audio input module AIM, or the like, based on a touch signal provided from the display module 300.

The wireless communication module TM may transmit/receive a wireless signal to/from other terminals using a Bluetooth or Wi-Fi link. The wireless communication module TM may transmit/receive a voice signal using a general communication line. The wireless communication module TM may include a transmitter TM1 that modulates a signal to be transmitted and transmits the modulated signal and a receiver TM2 that demodulates the received signal.

The image input module IIM may process an image signal and may convert the image signal into image data that may be displayed through the display module 300. The audio input module AIM may receive an external sound signal through a microphone in a record mode or a voice recognition mode and may convert the external sound signal to electrical voice data.

The external interface IF may serve as an interface between the control module CM and external devices, such as an external charger, a wired/wireless data port, a card socket e.g., a memory card and a SIM/UIM card, etc.

The second electronic module EM2 may include an audio output module AOM, a light emitting module LM, a light receiving module LRM, and a camera module CMM. The components may be mounted directly on the mother board, may be electrically connected to the electronic panel EP via a connector (not shown) after being mounted on a separate substrate, or may be electrically connected to the first electronic module EM1.

The audio output module AOM may convert the sound data provided from the wireless communication module TM or the sound data stored in the memory MM and may output the converted sound data to the outside.

The light emitting module LM may generate a light and may output the light. The light emitting module LM may emit an infrared ray. The light emitting module LM may include an LED element. The light receiving module LRM may sense the infrared ray. The light receiving module LRM may be activated when an infrared ray having a selected level or higher is sensed. The light receiving module LRM may include a complementary metal oxide semiconductor (CMOS) sensor. The infrared ray generated by and output from the light emitting module LM may be reflected by an external object, e.g., a user’s finger or face, and the reflected infrared ray may be incident into the light receiving module LRM. The camera module CMM may take an image of an external object.

According to an embodiment, the electronic module 400 shown in FIG. 2A may include at least one of the components of the second electronic module EM2. For example, the electronic module 400 may include at least one of a camera, a speaker, a light sensing sensor, and a heat sensing sensor. The electronic module 400 may sense the external object via the first area A1 or may provide a sound signal, such as a voice, to the outside through the first area A1. The electronic module 400 may include multiple components, and is not particularly limited thereto. Although not shown in figures, the electronic module 400 may be attached to the electronic panel EP by a separate adhesive.

Referring to FIG. 2A again, the housing 200 may be coupled to the window 100. The housing 200 may be coupled to the window 100 to provide an inner space. The display module 300 and the electronic module 400 may be accommodated in the inner space.

The housing 200 may have a material with a relatively high rigidity. For example, the housing 200 may include a glass, plastic, or metal material or frames and/or plates of combinations thereof. The housing 200 may stably protect the components of the electronic device 1000 accommodated in the inner space from external impacts.

FIG. 3 is an schematic diagram of an equivalent circuit diagram illustrating the pixel PXij of the display module 300 according to an embodiment. The pixel PXij, a first pixel disposed in the first area A1, and a second pixel disposed in the second area A2 have a difference only in size, and thus, the equivalent circuit diagram of the pixel PXij may be applied to the first pixel and the second pixel.

FIG. 3 shows the pixel PXij connected to an i-th scan line SLi among scan lines SL1 to SLn of a first group and a j-th data line DLj among data lines DL1 to DLm.

In an embodiment, a pixel driving circuit may include first to seventh transistors T1 to T7 and a capacitor Cst. In an embodiment, each of first, second, third, fourth, fifth, sixth, and seventh transistors T1 to T7 will be described as a P-type transistor, however, the embodiments are not limited thereto. The transistors T1 to T7 may be implemented by a P-type transistor or an N-type transistor.

In an embodiment, at least one of the transistors T1 to T7 may be omitted. At least one of the transistors T1 to T7 may include a semiconductor layer containing oxide, and the other of the transistors T1 to T7 may include a semiconductor layer containing silicon.

The first transistor T1 may be a driving transistor, and the second transistor T2 may be a switching transistor. The capacitor Cst may be electrically connected between a first power line PL to which a first power supply voltage ELVDD is applied and a reference node RD. The capacitor Cst may include a first electrode Cst1 electrically connected to the reference node RD and a second electrode Cst2 electrically connected to the first power line PL.

The first transistor T1 may be electrically connected between the first power line PL and an electrode of a light emitting diode OLED. A source S1 of the first transistor T1 may be electrically connected to the first power line PL.

Each of the first light blocking opening OP-BM1 and the second light blocking opening OP-BM2 of the black matrix BM may define a pixel area PXA. The pixel area PXA may be defined as an area from which the light generated by the light emitting diodes OLED-A and OLED-B are emitted to the outside. As the size of the pixel area PXA increases, the luminance of the image may increase. A non-pixel area NPXA may be defined adjacent to the pixel area PXA and may be defined as the remaining area excluding the pixel area PXA, and the non-pixel area NPXA may surround the pixel area PXA.

In the first area A1, the width of the cross-section of the first light blocking opening OP-BM1 of the black matrix BM may be greater than the width of the corresponding first light emitting opening OP-P1 of the pixel definition layer PDL. In the second area A2, the width in the cross-section of the second light blocking opening OP-BM2 of the black matrix BM may be greater than the width of the corresponding second light emitting opening OP-P2 of the pixel definition layer PDL.

In a plan view, the size of the first light blocking opening OP-BM1 of the black matrix BM may be greater than the size of the corresponding first light emitting opening OP-P1 of the pixel definition layer PDL. In a plan view, the size of the second light blocking opening OP-BM2 of the black matrix BM may be greater than the size of the corresponding second light emitting opening OP-P2 of the pixel definition layer PDL.

The color filter layers CF1 and CF2 may be disposed on the third sensing insulating layer 93 and may cover the black matrix BM. The color filter layers CF1 and CF2 may selectively transmit the light provided from the light emitting layer EML.

According to the embodiment, the color filter layers CF1 and CF2 may include a first color filter layer CF1 overlapping the first area A1 and a second color filter layer CF2 overlapping the second area A2.

According to the disclosure, the first color filter layer CF1 may have a first thickness TH1 in the cross-sectional view. The second color filter layer CF2 may have a second thickness TH2 in the cross-sectional view. In the disclosure, the thickness of the color filter layer may be defined by a distance from a surface of the color filter layer contacting the third sensing insulating layer 93, to the other surface of the color filter layer, which may be the opposite surface in the thickness direction. The thickness of each of the color filter layers CF1 and CF2 may be the thickness of a color filter layer in an area overlapping the pixel area PXA. For example, the thickness of the color filter layer may be a minimum thickness in the area overlapping the pixel area PXA.

According to the disclosure, the first thickness TH1 of the first color filter layer CF1 may be smaller than the second thickness TH2 of the second color filter layer CF2. The first thickness TH1 may have a value of about 60% to about 90% of the second thickness TH2.

According to the disclosure, as the thickness of the color filter layer is different in the first and second areas A1 and A2, the luminance lifetime of the light provided from the display panel 310 may be controlled. In the disclosure, the luminance lifetime means a time during which the luminance is maintained within a range from about 90% to about 97% of the luminance value that is first measured in the display panel 310 when the display panel 310 is manufactured.

The luminance lifetime is inversely proportional to the current density. Thus, the luminance lifetime may depend on the size of the light emitting openings OP-P1 and OP-P2. The luminance lifetime also depends on the light transmittance of the color filter layers CF1 and CF2. In the disclosure, the transmission area BT (refer to FIG. 4 ) of the first area A1 is set according to the requirements of the camera of the product to perform. The light blocking area BA may be defined as the remaining area excluding the previously set transmission area BT. Therefore, in the first area A1, there is a limit to how much the size of the light emitting openings OP-P1 may be increased in the light blocking area BA.

Accordingly, according to the disclosure, as the first thickness TH1 of the first color filter layer CF1 disposed in the first area A1 is reduced, the transmittance with respect to the light provided through the first light emitting opening OP-P1 may increase, and thus, the luminance lifetime may be improved without increasing the size of the first light emitting opening OP-P1.

Where there is no difference in thickness between the first and second color filter layers CF1 and CF2, the luminance lifetime of the first area A1 may be different from the luminance lifetime of the second area A2. According to the disclosure, as the relatively lower luminance lifetime of the first area A1 increases, the luminance lifetime in the first area A1 and the luminance lifetime in the second area A2 may become substantially similar, and a display quality of the electronic device 1000 (refer to FIG. 1 ) may be improved.

According to an embodiment, the difference between the first thickness TH1 and the second thickness TH2 may be equal to or greater than about 0.3 micrometers and equal to or smaller than about 1.5 micrometers. When the difference between the first thickness TH1 and the second thickness TH2 is smaller than about 0.3 micrometers, the difference in light transmittance between the first color filter layer CF1 and the second color filter layer CF2 may not be sufficient to reduce the difference in the luminance lifetime between the first and second areas A1 and A2. This may also apply when the first thickness TH1 has a value greater than about 90% of the second thickness TH2.

When the difference between the first thickness TH1 and the second thickness TH2 is greater than about 1.5 micrometers, the first color filter layer CF1 may not function smoothly as the first thickness TH1 becomes thinner. It may also be difficult to perform a deposition process of the second color filter layer CF2 as the second thickness TH2 becomes thicker. This may also apply when the first thickness TH1 has a value smaller than about 60% of the second thickness TH2.

The overcoat layer OC may be disposed on the color filter layers CF1 and CF2 and the black matrix BM. The overcoat layer OC may surround concave and convex portions formed in the process of forming the color filter layers CF1 and CF2 and the black matrix BM to provide a flat surface. The overcoat layer OC may be a planarization layer. The window 100 (refer to FIG. 2A) may be coupled to the flat surface of the overcoat layer OC by an adhesive layer.

According to the embodiment, the light blocking layer BML may be disposed in the light blocking area BA of the first area A1. The light blocking layer BML may overlap the light blocking area BA and may not overlap the transmission area BT of the first area A1. The light blocking layer BML may be disposed between the second barrier layer BRL and the buffer layer BFL.

The light blocking layer BML may serve as a mask pattern when forming the opening CE-OP of the second electrode CE described below in FIG. 5B. For example, a light, such as a laser beam, may be provided to the second electrode CE from the rear surface of the base layer BS. The laser beam may reach a portion of the second electrode CE after passing through an opening BML-OP (refer to FIG. 5B below) of the light blocking layer BML. The portion of the second electrode CE may be removed by the light (the laser beam) provided through the opening BML-OP of the light blocking layer BML. The light blocking layer BML may prevent components disposed on the light blocking layer BML from being damaged by the laser beam.

The light blocking layer BML that may be disposed on the second barrier layer BRL to prevent conductive materials disposed on the base layer BS and the second barrier layer BRL from being recognized as the electronic module 400 (refer to FIG. 2A) due to the external light. Accordingly, although the electronic module 400 is disposed in the display area DA (refer to FIG. 2A), interference with the conductive materials disposed on the base layer BS and the second barrier layer BRL may be reduced, and thus, the performance of the electronic module 400 of the electronic device 1000 may be improved.

Referring to FIG. 5B, the first area A1 may include the light blocking area BA in which the first pixel EP1M is included and the transmission area BT adjacent to the light blocking area BA. The transmission area BT may be defined as an area in which the conductive materials or the insulating layers are patterned or are not deposited to improve the light transmittance.

In an embodiment, the light blocking layer BML, the first insulating layer 10, the second insulating layer 20, the third insulating layer 30, the fourth insulating layer 40, the fifth insulating layer 50, and the seventh insulating layer 70 among the first to seventh insulating layers 10 to 70, which are included in the display panel 310 (refer to FIG. 5A), may not be formed in the transmission area BT or may be patterned away after being deposited. Accordingly, the light blocking layer BML, the first to fifth insulating layers 10 to 50, and the seventh insulating layer 70, which overlap the light blocking area BA, may not overlap the transmission area BT.

A side surface of the light blocking layer BML, which defines the opening BMI,-OP, may be covered by the buffer layer BFL that is not patterned. The barrier layer BRL exposed through the opening BML-OP of the light blocking layer BML may also be covered by the buffer layer BFL.

The first to fifth insulating layers 10 to 50 may be provided with a transmission opening IL-OP defined (surrounded) by their side surfaces formed through a patterning process, and the side surfaces that define the transmission opening IL-OP may be covered by the sixth insulating layer 60 among the organic insulating layers. The sixth insulating layer 60 may not be patterned away.

In the transmission area BT, the second electrode CE among components of the light emitting diode OLED-A may not be deposited or may be patterned away after being deposited.

According to an embodiment, the hole control layer HCL and the electron control layer ECL may not be patterned and may be disposed to overlap the transmission area BT. A side surface of the second electrode CE, which defines the opening CE-OP, may be covered by the first sensing insulating layer 81.

The black matrix BM and the first color filter layer CF1 may not overlap the transmission area BT. The overcoat layer OC may be disposed on the third sensing insulating layer 93 in the transmission area BT and may contact the third sensing insulating layer 93.

According to the embodiment, the overcoat layer OC may be disposed in the transmission area BT to cover a base layer portion BS-P, a second barrier layer portion BRL-P, a buffer layer portion BFL-P, a sixth insulating layer portion 60-P, a hole control layer portion HCL-P, an electron control layer portion ECL-P, a first inorganic layer portion 81-P, an organic layer portion 82-P, a second inorganic layer portion 83-P, a first sensing insulating layer portion 91-P, a second sensing insulating layer portion 92-P, and a third sensing insulating layer portion 93-P.

The organic layer 82 of the thin film encapsulation layer TFL may have different thicknesses depending on areas to compensate for a step difference between the insulating layers that are not deposited or are patterned after being deposited in the transmission area BT. For example, the thickness of the organic layer 82 in an area overlapping the transmission area BT may be greater than the maximum thickness of the organic layer 82 in areas overlapping the second area A2 and the light blocking area BA.

According to the disclosure, the first area A1 may have a light transmittance higher than that of the second area A2, and the transmission area BT may have the highest light transmittance in the first area A1.

According to an embodiment, a portion of an upper surface BM-U of the black matrix BM adjacent to the transmission area BT may be covered by the first color filter layer CF1. The other portion of the upper surface of the black matrix BM adjacent to the transmission area BT may be exposed without being covered by the first color filter layer CF1 and may be covered by the overcoat layer OC.

FIG. 7 shows the shape of the step difference area of the first right pixel E11-R and the second left pixel E13-L as an example. However, the shape of the step difference area may be changed by according to the design of the transmission area BT.

Among the first-first sub-pixels E11M, the first left pixel E11-L may include a first lower side L1 adjacent to the transmission area BT and extending in the first direction DR1, a second lower side L2 extending from the first-first long side L-B1 to the second direction DR2, and a third connection side C3 extending in the fifth direction DR5 and connecting the first lower side L1 and the second lower side L2.

The first left pixel E11-L may have a pentagonal shape defined by removing a portion of the left side from the rectangular shape defined by the sides extending in the first and second directions DR1 and DR2.

Among the first-third sub-pixels E13M, the second right pixel E13-R may include a third lower side L3 adjacent to the transmission area BT and extending in the first direction DR1, a fourth lower side L4 extending from the third-second long side L-R2 to the second direction DR2, and a fourth connection side C4 extending in the fifth direction DR5 and connecting the third lower side L3 and the fourth lower side L4.

The second right pixel E13-R may have a pentagonal shape defined by removing a portion of the right side from the rectangular shape defined by the sides extending in the first and second directions DR1 and DR2.

According to an embodiment, the first upper side U1 of the first right pixel E11-R, the long side adjacent to the transmission area BT of the second long sides L-G of the first center pixel E12-1, and the second upper side U2 of the second left pixel E13-L may be aligned in a row with respect to the second direction DR2. The second lower side L2 of the first left pixel E11-L, the long side adjacent to the transmission area BT of the second long sides L-G of the fourth center pixel E12-4, and the fourth lower side L4 of the second right pixel E13-R may be aligned in a row with respect to the second direction DR2.

However, the embodiments are not limited regarding the alignment of the sub-pixels. For example, the first upper side U1 of the first right pixel E11-R and the second upper side U2 of the second left pixel E13-L may be disposed to overlap the second short side S-G of the first center pixel E12-1 with respect to the second direction DR2. The second lower side L2 of the first left pixel E11-L and the fourth lower side L4 of the second right pixel E13-R may be disposed to overlap the second short side S-G of the fourth center pixel E12-4 with respect to the second direction DR2.

In the second case described with reference to FIG. 6B, the first-first short side S-B1 and the first-first long side L-B1 of the first left pixel E11-L among the first-first sub-pixels E11M and the first-second short side S-B2 and the first-second long side L-B2 of the first right pixel E11-R among the first-first sub-pixels E11M may have a relatively large width compared to the first case.

In the second case, the second short side S-G and the second long side L-G of each of the first-second sub-pixels E12M may have a relatively large width when compared to the first case.

In the second case, the third-first short side S-R1 and the third-first long side L-R1 of the second left pixel E13-L among the first-third sub-pixels E13M and the third-second short side S-R2 and the third-second long side L-R2 of the second right pixel E13-R among the first-third sub-pixels E13M may have a relatively large width compared to the first case.

The difference in width between a side of the first-first, first-second, and first-third sub-pixels E11M, E12M, and E13M in the second case and a side of corresponding sub-pixels in the first case may be equal to or greater than about 0.2 micrometers and equal to or smaller than about 15 micrometers. The size of the first light emitting opening OP-P1 of each of the first-first, first-second, and first-third sub-pixels E11M, E12M, and E13M in the second case may be greater than that in the first case.

Accordingly, a distance between the first-first, first-second, and first-third sub-pixels E11M, E12M, and E13M in the second case may be smaller than that in the first case. The width of the pixel definition layer PDL disposed between the sub-pixels may be reduced.

The difference in thickness between the first and second color filter layers CF1 and CF2 in the second case may be greater than that in the first case, and the size of the first light emitting openings OP-P1 of the pixel definition layer PDL of the light blocking area BA in the second case may be greater than that of the first case. Accordingly, the electronic device 1000 (refer to FIG. 1 ) in the second case may provide light with a relatively higher luminance in the light blocking area BA than the electronic device 1000 in the first case. The lifetime with respect to the light having the relatively higher luminance than that of first case may increase.

Accordingly, the thickness of the color filter layers CF1 and CF2 and the size of the first light emitting openings OP-P1 of the electronic device 1000 may be adjusted. Thus, the performance of the electronic module 400 may be improved, and the display quality of the image provided through the display module 300 may be improved.

The second-first, second-second, and second-third sub-pixels E21M-2, E22M-2, and E23M-2 of the second pixel E12M-2 may also be arranged in a PENTILE™ structure.

For example, the second-first sub-pixel E21M-2 may have a square shape defined by the fourth direction DR4 and the fifth direction DR5. The second-first sub-pixel E21M-2 may have a lozenge shape with respect to first-first sub-pixels E11M emitting the same color among sub-pixels E11M, E12M, and E13M disposed in a first area A1.
